Summary

This study compares two versions of the Nuss surgery for pectus excavatum (sunken chest) in teenagers aged 11 to 18. Researchers will look at 80 patients' records to see which technique leads to shorter surgery, less pain, and better cosmetic results. The goal is to help surgeons pick the best method for future patients.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
surgical procedure (modified Nuss technique vs. classic Nuss technique)
What this could lead to
If this study finds one technique is better, it could help surgeons choose the best approach for teens with pectus excavatum, leading to shorter operations and better recovery.
What could go wrong
This is a small, single-center retrospective study, not a large randomized trial. Results may not apply to all patients or hospitals, and the study only looks back at past records.
